Human Hand Practice - Scribble Art

Here is my new art work. It's a human hand Practice.
This time. I drew with a traditional medium which is pen.

I tried exploring two hands of an ageing man resting on a rod. While sketching, I has a few strokes trespassing the fingers' boundaries.

The drawing was done with a blue ballpoint pen on a cardboard paper using scribble style. You can see my steps below:

Thank you.
